To all whom it may concern:

Be it known that I, KAzIMnnAs LAPtNs- KAS, a citizen of Russia, residingat Union City, county of New Haven, and State of Connecticut, haveinvented certain new and useful Improvements in Undersea Destroyers, ofwhich the following is a specification.

This invention relates to improvements in apparatus adapted to engagedestructive devices with the hulls of ships and has as its specialobject the provision of a submergible boat adapted to convey an operatorin such a manner that he may be enabled to attach a bomb to the hull ofan enemy ship whereby it may be destroyed.

A further object is to provide means whereby the operator is enabled tomanually cause attachment between the bomb and the hull at any desiredpoint therealong, so that the more vulnerable parts of the ship may bedamaged.

These and similar objects are attained by the novel construction andcombination of parts hereinafter described and shown in the accompanyingdrawings, forming a material part of this disclosure, and in whichFigure l is a side elevational View showing a conventional type of shipand indicating the operation of the invention.

Fig. 2 is a side elevational view of the subinergible boat.

Fig. 3 is a horizontal sectional view taken substantially on the centerline of the same.

Fig. 4c is an enlarged transverse sectional view taken on line H of Fig.3, and

Fig 5 is a perspective view showing a preferred form of the bomb used inconnection with the boat.

Referring to the drawings, the numeral 10, designates a conventionaltype of'a sea going ship provided with all the usual and necessaryparaphernalia and mechanism for its propulsion and navigation.

The undersea boat, indicated generally by the numeral 15, is comprisedof an ovoidal casing 16, having symmetrically rounded ends 17, thecasing being provided'with a ballast or weight 18, by which it is heldin a normally upright position.

On the upper side of the casing is an opening 20, normally covered by adome 521,

having curved flanges 22, held in position on the casing by a ring 23secured by screws" 24, the arrangement being such as to pro-' vide awater tight covering through which the operator may enter the boat.

Interior walls 25 extend downwardly Patented Apr. 8, i919.

from the opening 20, the same being bent to. I

form a seat 26, which continues an element 27, forming a water tightcompartment 28 for the operator, while rearward of the partition isanother compartment 29 above the' ballast 18, this compartment havingahorizontal flooring 30, which extends to the rear end of the casing,and has positioned therein a pump 31, driven-by a chain 32, trained overa gear on the motor 33.

Rearward of the chamber 29 is a vertical partition 34., divided intotwoportions by horizontal fioorings 30 the upper portion 36 being adaptedto contain water, as 15 a similar chamber 37 at the front of the boat,and enterable into these chambers are pipes, respectively 38 and 39,through which water may be passed from one'to the otherby action of thepump 31, thus aid'ordin ,ineans whereby the submergible boat may tiltedby changing the water in thecompartments.

In the lower compartment 29, over the ballast 18, is a storage battery38, leading to a switch and controlling device 39, in the chamber 28, bywhich'the motor i0 may be energized, this motor drives the chain 41 andby it a propeller shaft 42, extending through. the end of the boat andhaving attached to it a propeller (i=3, by which the boat is propelledthrough. the water. i

Energy from the storagebattery 38' also passes through a controllingdeyice 44:, whereby the motor 33- may be energized when desired. Thewall 4-5 of the chamber 28 is inclined forward so as to provide room forthe operator. The chamber :6 is open to the water through the passagesl? and is adapted to contain a store of the bombs 50, which may bepassed outward through the opening 47 by extending the arms of theoperator through openings 48 formed in the sides of the casing, therebeing engaged with the edges of the openings 48, impervious flexiblesleeve-like attachments 52 through which the hands 53 may pass, it beingpossible to enter the hands through the openings 47, and engagethebombs, towhich are attached powerfulr negnets 51, adapted m adhere tothe metallic hull of the ship 10 at any point along its surface.

In operation, the casing being carried upon the deck of the mother ship,the operator may enter, after which the dome 21 is secured in positionand the submergible lowered into the water.

The operator is then able, by the various electrical controls, to tiltthe-boat in any desired direction and to operate the same, eitherbackward or forward, maneuverlng as usual until the boat has arrivedbelow the hull of the ship to be destroyed, whereupon the arms areextended, a bomb extracted use, what I claim as new and desire to secureby Letters Patent, is y In a device of the class described, thecombination with a hollow submergible casing, having a plurality ofwater tight compartments formed therein, a plurality of bombs carried inone of said compartments, said bombs having magnets formed thereon, andimpervious flexible sleeve-like attachments formed through the sides ofsaid casing permitting'an operator to manually extract one or more bombsfrom said compartment and attach the magnet formed thereon to the hullof an adjacent ship.

In testimony whereof I have afiixed my signature.
